Welcome to TADA!

TADA is a draft R package being developed to help states, tribal nations, and other stakeholders compile and evaluate Water Quality Portal (WQP) data collected from surface water monitoring sites on streams and lakes more efficiently. TADA is also being used to as building block to support development of the TADA R Shiny application.

We encourage stakeholders to begin testing the functionality and providing feedback. Moreover, open source software provides an avenue for water quality program owners to develop and share code, and we welcome your contributions! More information on how to contribute can be found in the CONTRIBUTING.md file. We hope to build a collaborative community dedicated to this effort where contributors can discover, share and build the package functionality over time.

Water Quality Portal

In 2012, the WQP was deployed by the U.S. Geological Survey (USGS), the U.S. Environmental Protection Agency (USEPA), and the National Water Quality Monitoring Council to combine and serve water-quality data from numerous sources in a standardized format. The WQP holds over 420 million water quality sample results from over 1000 federal, state, tribal and other partners, and is the nation’s largest source for single point of access for water-quality data. Participating organizations submit their data to the WQP using the EPA’s Water Quality Exchange (WQX), a framework designed to map their data holdings to a common data structure.

Open-Source Code Policy  

Effective August 8, 2016, the OMB Mandate: M-16-21; Federal Source Code Policy: Achieving Efficiency, Transparency, and Innovation through Reusable and Open Source Software applies to new custom-developed code created or procured by EPA consistent with the scope and applicability requirements of Office of Management and Budget’s (OMB’s) Federal Source Code Policy. In general, it states that all new custom-developed code by Federal Agencies should be made available and reusable as open-source code.

The EPA specific implementation of OMB Mandate M-16-21 is addressed in the System Life Cycle Management Procedure. EPA has chosen to use GitHub as its version control system as well as its inventory of open-source code projects. EPA uses GitHub to inventory its custom-developed, open-source code and generate the necessary metadata file that is then posted to code.gov for broad reuse in compliance with OMB Mandate M-16-21.
